If you watch TV on your Mac and been annoyed by the constant buzzing of the Vuvuzela’s during the World Cup games, you might want to try this tip.
I use the equinux TubeStick to watch TV (full disclosure: I work for equinux) so this tutorial was written for The Tube, but it’ll work with other software or online streaming sites as well.
My colleague has put together a small application that eliminates the need to use Garageband. Check it out for even easier Vuvuzela filtering.
Step 1: Install & Configure Soundflower
Download the free Soundflower utility from Google Code. This utility allows you to pass audio from all applications back into your system, allowing us to filter it using Garageband.
- Open System Preferences > Sound
- Select Output: Soundflower (2ch)
- Select Input: Soundflower (2ch)
Your audio will now be muted – don’t worry, this is normal.
Step 2: Install VuvuX
There are other ways to filter out the buzz of the Vuvuzela’s manually, but Prosoniq offer a free AU plugin that takes care of it for you. Download it, then drag it onto the ‘Components’ alias:
Step 3: Start filter with Garageband
Prosoniq suggest using their filter with Audio Hijack Pro, but if you’d like to save yourself $32, you can use Garageband which probably came free with your Mac.
Simply launch Garageband, create a new real instrument project and adjust these settings:
- Go to Garageband > Preferences > Audio/Midi and select Audio Input: Soundflower (2ch)
- Go to your real instrument track, select the Edit tab and click a blank slot to add a new effect
- Choose VuvuX from the drop down list and make sure it is turned on
- Switch back to the Browse tab, select Input Source: Soundflower (2ch) and turn on the Monitor
You should now hear audio again. Now fire up The Tube and you will notice that Vuvuzela’s are a fair bit quieter. Turn the filter on or off to really hear the difference. You can also click the filter in Garageband to manually adjust the level of noise reduction – be careful though, too much reduction will cause the commentary and other game sounds to sound distorted.
Any there you have it! Enjoy a vuvuzela-free World Cup!
